Invasive Species Quizs

How can invasive species affect human activities?

• By improving crop yields and enhancing biodiversity.

• By damaging crops, clogging waterways, and increasing costs for management and control.

• By providing new habitats for native species.

• By reducing the need for pest control measures.

What is extinction?

• Complete disappearance of a species from earth, like the Megaladon shark.

• A gradual decline in the population of a species.

• The process of adaptation to a new environment.

• The increase in the number of individuals in a species.

What is the difference between accidental and intentional introduction of invasive species?

• Accidental introduction occurs through human activities, while intentional introduction happens naturally.

• Accidental introduction occurs without human intent, such as through ballast water, while intentional introduction is when humans deliberately introduce a species for purposes like agriculture or gardening.

• Accidental introduction is always harmful, while intentional introduction is always beneficial.

• Accidental introduction refers to species that are native to the area, while intentional introduction refers to non-native species.

What happens when a new predator is introduced to a food chain?

• The predator increases the population of its prey.

• The predator has no effect on the food chain.

• The predator can decrease the population of its prey, affecting the entire food chain.

• The predator eliminates all other species in the food chain.

What is biodiversity?

• The variety of life in the world or in a particular habitat or ecosystem.

• The number of species in a specific area.

• The total biomass of all organisms in an area.

• The genetic variation within a species.

What are zebra mussels?

• Small, freshwater mussels that are considered an invasive species in North America, known for clogging pipes and disrupting local ecosystems.

• A type of fish found in the Atlantic Ocean.

• A species of bird native to Africa.

• A type of plant that grows in wetlands.

What is the role of humans in the spread of invasive species?

• Humans have no impact on the spread of invasive species.

• Humans contribute by transporting invasive species through trade and travel.

• Humans only spread invasive species through gardening practices.

• Humans are responsible for the extinction of native species.

Why are invasive species often successful in new environments?

• They have a higher reproductive rate than native species.

• They may have few or no natural predators in the new environment, allowing their populations to grow unchecked.

• They are more adaptable to climate changes than native species.

• They can outcompete native species for resources due to their superior intelligence.

What is ballast water?

• Water used for drinking on ships

• Water taken on by ships to provide stability

• Water used for cleaning the ship's hull

• Water that is only found in freshwater lakes

What is extermination?

• A method to promote the growth of plants.

• The process of getting rid of an organism by killing it off, such as using herbicides to treat invasive weeds.

• A technique for breeding organisms in controlled environments.

• A strategy for conserving endangered species.
